Then I use this extension 2 draw patch 4x4 it works, then 5x5 works too.
But then I use 3x5 this doesnot work so as I expect. It seems that it draws 3x5 and then the last row connects with the first?
Does this extension unable to draw 3x3 meshes, or I'm making somthing wrong in my code ?

Probably I should read the extension before answering http://www.opengl.org/discussion_boards/ubb/wink.gif but here it goes:
What is the degree of the polynomial spline you want to evaluate?
You need at least degree+1 points to specify the spline.
